Notification device and notification method

A computer-implemented method for notifying the method comprising:

• storing, based on a communication between a first terminal and a candidate terminal through a first transfer node and a candidate transfer node, a combination of data including:
• a terminal identifier corresponding to the first terminal,
• first locator information associated with the first transfer node to which the first terminal is connected,
• a candidate terminal identifier corresponding to the candidate terminal, and
• candidate locator information indicating the candidate transfer node to which the candidate terminal is connected during the communication between the first terminal and the candidate terminal;
• acquiring, from a second transfer node to which the first terminal is newly connected, second locator information, wherein the second locator information is associated with the second transfer node, and wherein the second transfer node is distinct from the first transfer node;
• acquiring the terminal identifier corresponding to the first terminal;
• storing the second locator information and the terminal identifier;
• retrieving, based on the terminal identifier, the combination of data including the candidate terminal identifier and the candidate locator information;
• notifying the second transfer node the combination of data including the candidate terminal identifier and the candidate locator information;
• and
• causing the second transfer node to connect from the first terminal to the candidate terminal through the second transfer node and the candidate transfer node.

A system for notification, the system comprises:

• a processor;
• and
• a memory storing computer-executable instructions that when executed by the processor cause the system to execute a method comprising:
• storing, storage, based on a communication between a first terminal and a candidate terminal through a first transfer node and a candidate transfer node, a combination of data including:
• a terminal identifier corresponding to a terminal,
• first locator information associated with the first transfer node to which the first terminal is connected,
• a candidate terminal identifier indicating the candidate transfer node to which the candidate terminal is connected during the communication between the first terminal and the second terminal;
• acquiring, by an acquirer, from a second transfer node to which the first terminal is newly connected, second locator information, wherein the second locator information is associated with the second transfer node, and wherein the second transfer node is distinct from the first transfer node;
• notifying the second transfer node the combination of data including the candidate terminal identifier and the candidate locator information;
• and
• causing the second transfer node to establish a connect between the first terminal and the candidate terminal through the second transfer node and the candidate transfer node.
